sufficient passengers. The

congestion levels since this problem usually occur on the
congested sensitive spots.
c. Higher congestion levels cause
longer travel time, less trip numbers, inconvenience trips
and higher risks for passengers’ safety.
6. Poor accessibilities of prior to and
subsequent

2. TRAFFIC CONGESTIONS IN MEDAN
Factors Cause The Problem
1. The effects of changing the
land use functions in CBD area without
evaluating thoroughly the traffic management systems considering
overall road networks in Medan. For instance, the land use function in
Medan CBD area should be office complex in accordance with RTRWK
Medan The City Space Arrangement Plan
1995-2005. Therefore, the establishment of several commercial
buildings such as Mall Grand Palladium, the City Hall, the Crystal
Square and several condominiums in Medan CBD area without undertaking
an appropriate and thoroughly study on the regional transport systems in Medan
will cause the traffic problems become more severe and complex and also
severe financial losses on community due to the traffic congestion; total
financial losses for the travelers in Medan is Rp.1.3 millions per day or
Rp.36 billions per month please see the attached analysis in ANALISA
newspaper in OPINI column page 18 on Nov 19
th
2004 . 2.
Determining the traffic flow directions by spots and not taking
into account the whole road networks will definitely add more congestion
spots and levels in the road networks of Medan City. E.g. changing the two-way
traffic direction into one-way direction along Jalan Gatot Subroto due to the
existence of Medan Fair Plaza Carrefour without undertaking
appropriate transport systems study adds more congestion spots and levels
along the street and surroundings collector and local roads.
3. Lack of competent academics experts
and no Transport experts involved by the Medan City Government Pemko,
Pemprovsu, Bappeda, Dishub in giving academics based
inputsanalysis to find the best solutions for the city’s problems. The
involvement of competent academics experts will minimize the impacts of
“wrong men on the wrong place” of the high officialsfunctionaries of Medan
City.
4.
The effects of high side-frictions cause
narrowing the width of road lane bottleneck. The side-frictions for
instance are : a.
On-road parking. b.
Sellingmarket on the trotoirsidewalk or on-road
market. c.
On-road trishaws and angkots’
pools. d.
On-road social activities parties or funeral ceremony.
e. Poor pedestrian’ facilities : on-road
walking and road crossing. 5.
Ineffective management of the signalized andor unsignalized
intersections, such as follows : a.
Inappropriate design of intersection geometric the width, the slope,
minimum sight distance, turning radius, etc.
b. Incorrect setting of traffic light on
the intersections and poor coordination of integrated
signalized intersections.
c. Inappropriate canalization.
6.
Indiscipline behaviors of the motorists, e.g. stopping the vehicle
anywhere or overtaking suddenly to takedrop the passengers, driving the
vehicle with excessive speed and disobey the traffic lightrules.
7.
Imbalance ratio between road infrastructure development and the
growth rate of vehicles.
Suggested Solutions on Traffic Congestion Problems in Medan
